Submarine Scuffle is a battle game with a difference! The difference being that there is a possibility that your students can miss!
Split your class into 2 teams and ask them questions. If a team answers correctly, they can come up and launch a torpedo at 1 of the opposing teams submarines. But, if they touch the wrong part of the submarine, their torpedo will shoot over the top of the submarine, and miss! Each submarine will take 2 torpedo's before sinking.
